Japan's Stablecoin Act: The First Country to Legally Define 'Electronic Payment Instruments'

In July 2022, the Terra/Luna ecosystem collapsed. Within weeks, Japan’s Financial Services Agency had accelerated its stablecoin legislation timeline. By June 2023 — less than twelve months after the broader collapse — Japan had enacted the world’s first dedicated stablecoin law.

That speed is remarkable. Japan’s financial regulatory system is not known for rapid legislative response. The JFSA conducts thorough consultations, builds consensus across ministries, and prefers incremental reform. Yet on stablecoins, Japan moved faster than the United States, the European Union, and the United Kingdom — all of which were still consulting, deliberating, or passing interim measures at the point when Japan’s law took effect.

Understanding why requires understanding the specific architecture of Japan’s stablecoin legislation — and why that architecture was both easier to implement and more restrictive in its effect than any comparable framework.

The Legislative Context

Japan’s revised Payment Services Act had been in development before Terra/Luna’s collapse. The JFSA had been monitoring stablecoin developments globally and was already concerned about algorithmic stablecoins and inadequate reserve backing. Terra/Luna accelerated the legislative timeline and added urgency to the consultation process — but the policy direction had been set.

The JFSA’s fundamental position was that stablecoins designed to function as payment instruments should be regulated like other payment instruments. Japan has a mature, sophisticated framework for regulating fund transfer operators and electronic money issuers. The approach was to extend that framework to cover stablecoins, rather than creating an entirely new regulatory architecture.

The Legal Category: Electronic Payment Instruments

The revised Payment Services Act created a new legal category: “electronic payment instruments” (denshi shiharai shudan). This category is specifically defined to capture stablecoins that are designed for use as payment instruments — tokens pegged to fiat currencies, redeemable at par, and transferable on distributed ledger systems.

The definition is narrow and precise. Electronic payment instruments must be:

Pegged to a fiat currency — either Japanese yen or a foreign currency — at a fixed rate. Algorithmic stablecoins, which maintain their peg through supply adjustments rather than reserve backing, do not qualify as electronic payment instruments and remain in the broader cryptocurrency regulatory category.

Redeemable at par. Holders must be able to redeem their electronic payment instruments for the equivalent fiat value on demand. This is the hard standard that distinguishes genuine payment stablecoins from instruments that might trade at a discount.

Issued on a distributed ledger system or equivalent electronic infrastructure. The digital delivery mechanism is a definitional requirement.

Approved Issuer Types

The most consequential provision of Japan’s stablecoin legislation is its restricted list of approved issuer types. Only three categories of entity can issue electronic payment instruments under the revised Payment Services Act:

Banks licensed in Japan. This gives Japan’s major banking groups — MUFG, SMBC, Mizuho — the right to issue yen-pegged stablecoins, subject to their existing regulatory frameworks.

Trust companies licensed in Japan. The trust structure has been the preferred vehicle for asset tokenization in Japan, and its inclusion as an approved issuer type reflects the JFSA’s preference for trust-based backing mechanisms.

Licensed fund transfer operators. Japan’s fund transfer operator licence is the existing framework for non-bank electronic money services. Its inclusion creates a pathway for specialist stablecoin issuers — but the licensing requirements are substantial.

What is conspicuously absent from this list: technology companies, cryptocurrency exchanges, and non-bank fintech firms. There is no pathway for Tether, Circle, or any other established stablecoin issuer to distribute their products in Japan without a structural transformation — either obtaining a Japanese licence in one of the three approved categories, or partnering with a licensed entity.

Implications for Global Stablecoin Issuers

The implications of Japan’s issuer restrictions are significant and largely underappreciated outside Japan. USDC and USDT — the two dominant global stablecoins — cannot currently be offered to Japanese retail customers as “electronic payment instruments” under the revised Payment Services Act. They can still be traded as cryptocurrency, but their use as payment instruments is restricted.

For global stablecoin issuers, Japan represents a large and sophisticated market that is effectively closed without structural adaptation. Circle has been exploring partnerships with Japanese financial institutions. Tether has not publicly indicated a Japan-specific strategy.

The JFSA’s stance toward foreign stablecoins has been notably cautious. The agency has expressed concern about foreign stablecoin issuers operating outside Japanese oversight while serving Japanese customers — a concern that drives the stringent issuer requirements rather than any fundamental hostility to the stablecoin concept.

Comparison with GENIUS Act and MiCA

Japan’s stablecoin framework predates both the US GENIUS Act (signed July 2025) and MiCA’s full implementation (December 2024). The comparison is instructive.

The GENIUS Act broadly mirrors Japan’s structure: reserve backing requirements, redemption at par, restricted issuer categories (though the US list includes non-bank institutions through a separate licence pathway). Japan got there two years earlier.

MiCA’s e-money token (EMT) framework is structurally similar to Japan’s electronic payment instruments — fiat-pegged, reserve-backed, redeemable at par. The key difference is that MiCA’s e-money token issuer category is broader, including electronic money institutions that are not banks or trust companies, and allows for cross-border passporting within the EU.

Japan’s framework is the most restrictive of the three in terms of issuer eligibility — but also the most clearly defined. There is no ambiguity about who can issue electronic payment instruments in Japan.

Japan’s First-Mover Advantage

Japan’s stablecoin legislation gives it a distinctive position in the global policy debate: the country that moved first, that created the definitional template that others have referenced, and that demonstrated it was possible to enact dedicated stablecoin law without causing market disruption.

Whether Japan’s restrictive issuer framework proves to be a model that others adopt — or a cautionary example of over-restriction — remains to be seen. What is clear is that Japan’s 2023 legislation fundamentally changed the global policy conversation by proving it could be done.
